Description

DESCRIPTION

Flat Round Washer Sampson - Hot Dipped Galvanised - 1-1/8 (Box=20)

(Price per unit)

Flat washers are used to increase the bearing surface beneath a nut or bolt head, distributing the clamping force over a larger area.

They are particularly useful when fastening soft materials or components with oversized or irregularly shaped holes. A flat washer also provides a smooth, even surface for the nut or bolt head to bear against, helping to improve load distribution and reduce the risk of surface damage.

Flat washers are the standard washer used in most bolted connections and are typically installed beneath the nut, the bolt head, or both.

To ensure optimum strength, corrosion resistance, and long-term performance, flat washers should be selected from a material compatible with the bolt and nut. For example, use stainless steel washers with stainless steel fasteners, and galvanised washers with galvanised fasteners.

Applications

  • For use with high tensile grade 5 and above
  • Suitable for HDG imperial stud bolts

FLAT ROUND SAMPSON WASHER
 
Finish
HOT DIP GALVANISED
 
Galvanised is a dull greyish colour and rough in appearance. HDG products are used where a high level of corrosion resistance is required. HDG products are recommended for long term outdoor applications.
 
Note: galvanised washers are typically paired with galvanised fasteners to prevent uneven corrosion (called galvanic corrosion). Mixing them with non-coated or different metals can shorten their lifespan.
